SynCo Curriculum
Dataset Release for SynCo: Data Synthesis Co-Training for Self-Evolving LLMs via Multi-Agent Reinforcement Learning
📌 Overview
SynCo is a multi-agent reinforcement learning framework that jointly trains a Synthesizer and a Reasoner. As the Reasoner improves, the Synthesizer adapts the training distribution by generating new tasks near the learner's evolving capability boundary.
The SynCo Curriculum contains the mathematical reasoning problems produced through this online co-training process. Each example includes a problem statement and a verified final answer. An extended version additionally provides the Synthesizer's teaching intent, targeted Reasoner weakness, and estimated difficulty.
📊 Dataset Summary

🧾 Data Fields
| Field | Description |
|---|---|
id |
Unique example identifier |
generation_step |
Co-training step at which the problem was generated |
problem |
Mathematical reasoning problem |

The final three fields appear only in synco_curriculum_metadata.jsonl and should be treated as auxiliary model-generated annotations.
🚀 Usage
Load the compact dataset directly from the Hugging Face Hub:
from datasets import load_dataset
dataset = load_dataset(
"weiyang930/SynCo",
split="train",
)
print(dataset[0])
Load the extended metadata configuration with:
metadata_dataset = load_dataset(
"weiyang930/SynCo",
"metadata",
split="train",
)
✅ Quality Control
Answers were independently checked and corrected where necessary using complementary model-based solving, executable verification, mathematical equivalence checking, and manual review. Of the 2,940 problems used in the paper's curriculum, 26 were excluded from this release because they were ambiguous, under-specified, or did not admit a single well-defined answer. The final release therefore contains 2,914 problems.
The dataset preserves the generated curriculum order. Some semantically similar or repeated problems may remain, reflecting the data distribution encountered during co-training.
